Micro-Adjust CTS Deployant Clasp

The clasp is beautiful, micro adjusts system works well when extending the clasp although I do feel like I need to pull a little harder than I’d like to. My issue comes when I’m trying to put the clasp back to its original position. I have a very difficult time pushing the clasp back to the closed, smaller sized position. Especially with a malleable rubber strap.

Finally got my hands on the new Delugs Micro-Adjust CTS clasp — and this is a serious upgrade.
The biggest game changer is the on-the-fly micro-adjust system. You get up to 6mm of adjustment (3mm on each side), which makes a real difference throughout the day — especially with wrist swelling. No tools, no hassle, just a precise, instant fit whenever you need it.
What I really like is how Delugs kept the design sleek and minimal. It still has that clean look, but now with a much more refined mechanical feel. Every adjustment clicks in with a solid, premium snap.
Build quality is exactly what you’d expect — 316L steel, well-finished, and feels durable. Plus, it’s fully compatible with existing CTS rubber straps, which makes it an easy upgrade.
On my GMT Batman, it honestly elevates the whole wearing experience. Comfort is on another level now.

I’ve been using the Micro-Adjust CTS Deployant Clasp for a few days now, and it’s one of those small upgrades that ends up making a bigger difference than expected.

The concept is simple: on-the-fly micro-adjustment on a rubber strap, no tools needed. You just push or pull tthe strap through the clasp to fine-tune the fit. In daily use, that’s more than enough to get things exactly where you want them.

I’ll be honest, the first time I used it, it took a bit of trust. You’re applying pressure to a rubber strap and a mechanism you’re not familiar with, and there’s a brief moment of hesitation. But once you get past that and the system loosens slightly with use, it becomes very smooth and natural.

After that, it just works. Effortlessly.

What I like most is how it adapts to real life. Wrist size changes throughout the day, temperature, activity… and being able to make quick adjustments without having to fiddle and carry a small pin tool is something you get used to very quickly.

I’ve always enjoyed CTS straps for their fit and comfort, but this clasp takes the experience to another level.

For full transparency, I was able to try one first… and after using it, I’ve already bought two more to have all my CTS straps covered. That probably says everything about how I feel about it.

Not a necessity, of course, but a thoughtful upgrade that genuinely improves daily wear.
